org.json.JSONException:java.lang.String类型的值

据我所知...我收到了一个被 HTML 污染的字符串，但我不知道为什么!

我花了几个小时在互联网上研究这个问题，但没有找到任何匹配的回复。

如有任何建议，我们将不胜感激!

getuserdata.php 文件:

$pass = "";
$db = "uopuser";

$con=mysqli_connect("localhost", $user, $pass, $db) or die("Unable to connect");

$email = $_POST["email"];
$password = $_POST["password"];

$statement = mysqli_prepare($con, "SELECT * FROM User WHERE email = ? AND password = ?");
mysqli_stmt_bind_param($statement, "ss", $email, $password);
mysqli_stmt_execute($statement);

mysqli_stmt_store_result($statement);
mysqli_stmt_bind_result($statement, $user_id, $fname, $lname, $email, $password);

$user = array();

while(mysqli_stmt_fetch($statement)){
    $user[fname] = $fname;
    $user[lname] = $lname;
    $user[email] = $email;

}

echo json_encode($user);

mysqli_stmt_close($statement);

mysqli_close($con);

最佳答案

这是一个错误响应，可能与非 200 状态代码配对。

您需要服务器上的电子邮件参数，但您发送用户名。找不到 email 并且 php 产生错误。

您应该向您的服务器添加错误处理。要解决您的问题，请更改为服务器上的用户名或Java中的电子邮件。
